What Faribault winters do to a water heater
Your water heater works hardest from September through May, and on the coldest nights it is heating water that started out near 10°F. That is a bigger jump in temperature than it sees the rest of the year, and the burner or element runs longer to close that gap. Over time that extra run time wears on the thermostat and the heating element in an electric tank, or the burner assembly in a gas one.
Rice County also sees its share of winter storms and wind events that knock out power for stretches at a time. A gas water heater with a standing pilot keeps working through an outage. One with electric ignition will not fire until power is back, and when it comes back on, it should relight and heat on its own. If yours does not, that points to a problem with the ignition system itself, not just the outage.

A new water heater would cut about $50 a year off hot water for a typical Minnesota home.

Repair makes sense when an element, thermostat or gas valve has failed.
Replacement makes sense when the tank itself is leaking.
- Why is my water heater leaking from the bottom?
- The tank itself has likely rusted through from the inside and is starting to fail. Sediment builds up at the bottom of the tank over years and corrodes the metal until it develops a crack or pinhole. It could also be a loose drain valve or a fitting that just needs tightening, so a contractor will check those first before condemning the tank. Once the tank itself is leaking, the unit needs to be replaced, not repaired.
- Why won't the pilot light on my water heater stay lit?
- Most often the thermocouple has worn out and can no longer sense the flame, so the gas valve shuts off as a safety measure. A dirty pilot orifice or a draft blowing across the flame can cause the same thing. A weak or failing gas valve is possible too, though that shows up less often than a bad thermocouple. A contractor can test each part and tell you which one is actually failing.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Mineral scale on the heat exchanger, a failed igniter, or a clogged inlet filter are common issues and a contractor can clear or replace those parts. Error codes on the unit's display usually point straight to the cause. Homes here run water heaters hard for nine months of cold weather each year, so keeping the unit descaled matters for how long it lasts.
